Definitions

  • the present invention pertains to a system for providing access to secure data wherein access to secure data is controlled by secure data modules or cards in conjonction with a security scheme.
  • biometrics data as a reliable verification tool presents a great deal of problems.
  • Many biometrics systems still rely on the presentation of passwords or PIN codes as proof of an individual's identity.
  • passwords and PIN codes which are prone to misappropriation and forgetfulness, create weaknesses in such systems. People are prone to forget passwords, to make them obvious by selecting common or easily deciphered passwords or personal identification numbers (PINs), or to divulge passwords or PINs to other people.
  • Sophisticated security mechanisms are typically vulnerable to human error in situations when an essential element of the security system, such as a password, is held or utilized in a highly unregulated or careless manner.
  • an essential element of the security system such as a password
  • passwords are simple entities.
  • passwords have obvious deficiencies.
  • secured facilities require the storage of databases within the memory of a host computer system which contains permission data and controls access to the databases.
  • the password concept still facilitates the provision of secured data for a large and diverse group of individuals or other entities.
  • the password scheme for providing data access and security should be further isolated from the human element so that passwords and other related data may be stored consistently and in a secured manner. It would also be desirable if the password scheme could be adapted to a security scheme which could accommodate large hierarchies of users and data access requirements without requiring the use of multiple passwords or any passwords at all.
  • Document WO-A-97/22092 discloses a system in which medical information is encrypted on a user's/patient's smart card.
  • a medical professional smart card is used to decrypt and access said medical information.
  • the present invention relates to a system according to the pre-characterising portion of claim 1.
  • a system is known from WO-A-97/22092 .
  • the system of the invention is characterised by the characterising portion of claim 1.
  • the preferred embodiments of the present invention provide an improved data security and access control system which eliminates the need for multiple passwords for various operations and also prevents problems associated with conventional access cards which are generated and used in conjunction with passwords.
  • the preferred embodiments of the present invention overcome the problems of the prior art by providing a system for providing access to secured data using at least two secure data modules which contain security data and other information and which belong to a particular security scheme, and a dual module reader for reading data and permissions instructions contained on the secure data modules.
  • the two secure data modules include an enabling module and an interrogatable module.
  • the enabling module is preferably embodied in one of a plurality of media such as a data card (either contact or contactless type), a silicon chip or other suitable data storage device and is preferably contained in a module reader for reading an interrogatable module.
  • the interrogatable module may be embodied in the form of a data card or may also be in the form of a silicon chip or other suitable data storage device.
  • the interrogatable module and the enabling module communicate with each other via a dual module reader. Communication between the two modules is allowed as long as the two modules are members of the same security scheme.
  • a scheme is defined by suitable proprietary encryption keys for enabling communication and data transfer between the two modules belonging to a common scheme and for preventing communication and data transfer between two modules belonging to different schemes.
  • the enabling modules preferably contain data, which may be encrypted, which defines permissions.
  • the permissions defined by the data stored on the enabling module determines whether the module or card reader which is either contained in or operatively connected to the enabling module which is attempting to communicate with an interrogatable module can perform one or more of a plurality of data operations such as creating data, deleting data, reading data, writing data, and various other data functions to data contained on the interrogatable module.
  • the interrogatable module may preferably comprise a multi-application data card having any of a plurality of different types of data including personal identification data such as fingerprint data, three-dimensional facial image data, retina scan data; personal information such as name, address, marital status, etc.; financial and banking information; personal medical information; passport related information such as Visa and travel information; insurance information and any other suitable information relating to a user or holder of the interrogatable module.
  • personal identification data such as fingerprint data, three-dimensional facial image data, retina scan data
  • personal information such as name, address, marital status, etc.
  • financial and banking information personal medical information
  • passport related information such as Visa and travel information
  • insurance information and any other suitable information relating to a user or holder of the interrogatable module.
  • This data is encrypted using a suitable data encryption keys which belong to a desired security scheme.
  • the communication between the enabling module and the interrogatable module occurs in a dual module reader apparatus as follows.
  • the dual module reader apparatus includes an interrogatable module reader and an enabling module reader.
  • the interrogatable module is brought into contactless communication with the dual module reader.
  • the enabling module reader either contains the enabling module or is operatively connected, for example via a network connection, to the enabling module.
  • the dual module reader determines whether the enabling card and interrogatable card can interface or communicate.
  • the ability to interface is determined based on whether the enabling module and the interrogatable module belong to the same security scheme defined by encryption keys.
  • the interrogatable module and interrogatable module reader transmits a challenge to the enabling module via the enabling module reader to determine whether the enabling module is authorized to perform data operations to the data contained on the interrogatable module.
  • the ability of the enabling module and enabling module reader to perform the requested data operations on the interrogatable module is not determined based on entry of passwords as in the prior art but instead is determined in an isolated manner by the set of permissions contained in the enabling module. That is, in response to the challenge from the interrogatable module transmitted via the enabling module reader, the enabling module issues a response via the enabling module reader to the interrogatable module reader informing that reader whether the enabling module has permission to perform data operations on the interrogatable module data.
  • the response from the enabling module is negative and no data communication is allowed.
  • the enabling module and the enabling module reader send a challenge to the interrogatable module to determine if the holder of the interrogatable module has appropriate authority to conduct the requested data operations on that particular interrogatable module.
  • the determination of whether the holder of the interrogatable module is authorized to use the interrogatable module and conduct data operations is preferably determined by matching personal biometrics identification data contained on the interrogatable module with actual personal biometrics data obtained by the dual module reader from the holder of the interrogatable module at the time that such communication is attempted.
  • This matching of stored and actual personal biometrics data can be done via a suitable biometrics data collection device such as a facial image recognition system, a palm or fingerprint scanner, a retina scanner or other suitable biometrics data collection and comparison device.
  • a suitable biometrics data collection device such as a facial image recognition system, a palm or fingerprint scanner, a retina scanner or other suitable biometrics data collection and comparison device.
  • the determination of whether a holder of the interrogatable module has authority to conduct data operations on that card may also be done via a conventional password challenge and response exchange.
  • the enabling module reader and enabling module will issue a request for data to the interrogatable module to determine if the data which is contained on the interrogatable module and which is required to perform the data operation requested by the holder of the interrogatable module can be accessed by the enabling module. That is, any particular data record or any entire data set of data records may be unaccessible to the particular enabling module because the permissions contained on the enabling module do not allow the enabling module to access such data records or data sets.
  • the interrogatable module will respond to the request from the enabling module by issuing a challenge to the enabling module via the enabling module reader to determine whether the permissions stored on the enabling module allow the enabling module to access the requested data stored on the interrogatable module.
  • the enabling module may respond to the challenge from the interrogatable module by transmitting the permissions data indicating that the enabling module is authorized to access the requested data from the interrogatable module. If the enabling module does not provide the necessary permissions data in the form of a response to the challenge, the interrogatable module reader and interrogatable module prevent the requested data from being accessed by the enabling module and enabling module reader.
  • Each of the challenges and responses described above embodying the communication between the enabling module and the interrogatable module are encrypted according to an encryption scheme which is unique to a particular security scheme to which both the enabling module and interrogatable module must belong in order to communicate with each other. It is preferred that each security scheme have identification numbers which are unique within high degrees of statistical certainty. This unique scheme is used as a secret component in a data communication attempt between the enabling module and the interrogatable module to generate a one-time session key for that particular communication attempt. Challenges and responses during the particular communication attempt are encrypted with the unique session key and therefore allows only modules belonging to the same scheme to decrypt the messages.
  • a security scheme is set up via a controller module or card.
  • the controller card When initially setting up a security scheme, the controller card is programmed to have data or permissions which authorize all data operations. These permissions are not typical passwords, but rather, are much more sophisticated and flexible data structures which are stored on the secure data modules. Each permission can authorize the access or other data operation to a data set or data record stored on a secure data module. Further, each permission may or may not be conferred to other secure data modules.
  • the desired set of data operations includes:
  • This data is stored on the controller module using a suitable desired encryption scheme which is implemented using a plurality of encryption keys.
  • enabling modules and interrogatable modules can be made from the controller module. That is, the controller module can grant permissions to other modules or cards by writing permissions data to the module to make it an enabling card. Permissions data can also be written from the controller module or an enabling module to an interrogatable module. In this manner, hierarchical sets of permissions for data operations can be written to the modules.
  • an enabling module cannot empower another module with more permission than the enabling module itself contains.
  • the above-described security schemes and permissions data for enabling any of the data operations described above can be implemented using suitable proprietary software and conventional hardware. That is, the data operations implemented via a secure data module system including a dual module reader is preferably implemented and carried out via software programs executed on suitable computers and central processing units.

These keys are used to convert a blank data card into a controller card. Controller cards contain a full set of permissions and are thus capable of performing any task on any other data card within the same scheme. Any number of controller cards may be created provided that they are programmed with the same guardian keys and with the keys entered in the same order.

These keys may also be utilized to convert a blank data card into a controller card which contains a full set of permissions and are therefore, capable of performing any task on any other data card within the same scheme.
